Hey all,
I'm sure most of us have seen some version of a video and/or pictures of the shell-less egg experiments, especially the one with the news clip of Japanese students doing the experiment- this is a much clearer, much more methodical accounting of the process with great photography.
While I was waiting for some eggs to hatch (On my 7th broody already this year), I did a search and found a video I hadn't seen previously with BEAUTIFUL detail- each and every day is documented, and each day has its own little video clip once the heart starts beating.
They did a paper on it which can be found here: https://www.jstage.jst.go.jp/article/jpsa/51/3/51_0130043/_pdf/-char/en
So here it is- if you're not interested in the set-up part, skip forward to about minute 5:00 where the actual egg development begins. If the link doesn't work, just google "Observation of the Development of Chick Embryo", or type that into youtube. The total length is 9:45.
